West Notes: Perez, Cashner, Ibanez, La Russa

Rangers left-hander Martin Perez underwent his Tommy John surgery earlier today, and everything “went as expected,” writes Evan Grant of the Dallas Morning News. The surgery was performed by Dr. Keith Meister, who performs most of the club’s surgeries. As the Rangers look to deal with that blow to their rotation, here’s more from baseball’s Western divisions…

For the time being, Padres ace Andrew Cashner has avoided joining Perez on the list of series elbow injuries. Cashner underwent an MRI today, and while that test has conditioned the public to fear the worst, GM Josh Byrnes issued the following statement via press release: “After performing an MRI today on Andrew’s right elbow, our doctors have indicated to me that he has elbow soreness and irritation. Based on our doctors’ recommendation we will be proceeding with rest and rehabilitation for his recovery.”

Though the Angels will soon need to make roster moves to get Kole Calhoun, David Freese and Dane De La Rosa back on the active roster, releasing struggling DH Raul Ibanez isn’t likely, reports MLB.com’s Alden Gonzalez. General manager Jerry Dipoto wouldn’t say Ibanez will not be released, Gonzalez writes, but he expressed that the team will remain patient and voiced confidence in the aging slugger: “Raul has a track record. He has done this before. He has gone through cold spells, and he has gotten hot. There’s nobody here who believes Raul has had his last good days in the big leagues.”

Diamondbacks president Derrick Hall “can hardly stop pinching [himself]” after the team’s hiring of Tony La Russa as its new chief baseball officer, writes Jon Heyman of CBS Sports. La Russa drew interest from multiple clubs for an executive role and turned down at least one offer, feeling that he wasn’t needed with that team, Heyman adds. He also writes that manager Kirk Gibson has close to a clean slate following the La Russa hire, and that La Russa will give Gibson and GM Kevin Towers until at least season’s end to help get the Snakes back on track.
